Abstract :
The development of microstrip gas chambers manufactured on thin-foil plastic supports is described. Gains up to 10/sup 4/ and energy resolutions around 20% full width at half maximum (FWHM) have been obtained for low rate 5.9 keV X-rays. A space-charge-dominated gain drop appears only at very high rates, close to 10/sup 6/ s/sup -1/-mm/sup -2/. However, the measurements show long-term time-dependent modifications (charging up), particularly for high-resistivity supports. Nevertheless, the results are very encouraging and further developments may lead to the development of a new family of light, flexible detectors with high resolution.<>
